'dance, electronic, electropop, hip hop, rock, and R&B music originating in South Korea"
a somewhat catchy genre, its bands usually consists of attractive groups of both gender. Through the Internet it has gained worldwide popularity. Being in korean, it has been untested if its fans understand korean or they have no idea what the songs are about. Described by the Times as 'catchy but derivative' it is possibly the shallowest form of music ever to gain popularity. Known to cause various facebook posts, usually in all caps, about how much they heart k-pop. The names of the bands are ridiculous, such as 'Big Bang', 'Girls Generation' and '2pm'. These are, respectively, a scientific theory explaining the expansion of the universe, a process of which girls generate, and a time in the afternoon when eating may be considered 'a late lunch'. These are the meanings of the names obeying grammar, but may have some other meaning to the South Koreans, but one can only fathom what they think it means. These are still ridiculous names compared to the names of other, non-korean bands.

Korean pop music. The current fad in the 21st century which will have dominated the world by the 22nd century. Includes either solo artist or groups, killer choreography, sexy persons with amazing personalities, and awesome music videos

Donnacia: Oh, did you hear the latest song by the Wonder Girls?
Jason: Who's the Wonder Girls?
Donnacia: They're a South Korean girl group who sing K-Pop.
Jason: What's K-Pop?
Donnacia: Korean Pop! The most amazing the on earth!(:

Suzuki: Which is better K-Pop or J-Pop?
La'Tisha: I say K-pop 'cause it's more Americanized and unique. But J-Pop is still good.
Suzuki: Oh you pooper! I except you to say J-Pop, haha!
Kim Yeol-Hee: I think they both are equally amazing!(:

A genre of music hailing from the land of South Korea with an absurdly huge fanbase. It's basically just the same shitty American pop music with electronic melodies, auto-tune, and repetitive/unintelligent lyrics, but in Korean instead of English. The male American fans of K-Pop are usually only fans because they have a bad case of yellow fever, and think that listening to Asian music will make them get all of that Asian pussy. The female fans, are just kind of rabid and psychotic. Overall, shitty music with shitty fans. Come at me, weeaboos.

Everyone in the class noticed Brian listening to loud K-Pop and checking out the Asian chicks.

k-pop stands for korean popular music.
it is the pride of korea and one of the most popular music styles in asia.
In other words, it is the total opposite of the definision the other person. "the true korean" gave us.
^^
korean music is our pride.
don't make fun of it.
